Abstract:
Objective:To investigate the correlation and dose-response relationship of pulse pressure and pulse pressure index with metabolic syndrome in the elderly population.Methods:This was a cross-sectional study.A total of 114 212 subjects aged 65 years and over in Wujin District receiving health examination in 2019 were enrolled, including 40 388(35.4%)patients with metabolic syndrome.The survey contents included a questionnaire, physical examination and laboratory tests.Logistic regression and restricted cubic splines were used to analyze the correlation and dose-response relationship of pulse pressure and pulse pressure index with metabolic syndrome.Results:With increases in pulse pressure levels and pulse pressure index, the prevalence of metabolic syndrome and its components increased accordingly( P<0.01). After adjusting for confounding factors, the ORvalue of metabolic syndrome gradually increased along with increases in pulse pressure and pulse pressure index.Compared with the first quartile, pulse pressure and pulse pressure index in the second, third and fourth quartiles were correlated with metabolic syndrome(pulse pressure: OR=1.52, 95% CI: 1.47~1.58, OR=1.89, 95% CI: 1.82~1.96 and OR=2.15, 95% CI: 2.07~2.23, respectively; pulse pressure index: OR=1.22, 95% CI: 1.18~1.26, OR=1.36, 95% CI: 1.31~1.41 and OR=1.47, 95% CI: 1.42~1.53, respectively). Restricted cubic spline analysis showed that pulse pressure and pulse pressure index had non-linear dose-response relationships with metabolic syndrome( χ2=309.23 and 57.14, P<0.01). Conclusions:Pulse pressure and pulse pressure index are correlated and show non-linear dose-response relationships with metabolic syndrome and its components in the elderly.
